Abstract: A spring compression tool and method for using the spring compression tool in assembling a brake shoe adjustment mechanism on a WAGNER front brake. The tool includes a C-shaped body member and an adjustable portion. The body member includes a first end having a first clamping member, and a second end to which the adjustable portion is movably mounted. The adjustable portion includes a threaded shaft and a beam member. The beam member includes a plate and second and third clamping members. Rotation of the shaft moves the second and third clamping members relatively toward or away from the first clamping member. The tool is used to compress a brake shoe adjustment spring, and to maintain the spring in a compressed condition to permit assembly of other components of the adjustment mechanism.
